CheerMyRun reviews from the App Store.
Before you run
Can my family follow from another country?
Yes. Anyone with your link and an internet connection can follow your run and send voice cheers. They don’t need an app or account. Share your local start time so they know when to join.
What do I need on race day?
Carry your phone with GPS, mobile data and enough battery. Connect headphones to hear cheers, if the event permits them. Try a test run first; tracking and messages depend on signal and permissions.
Is CheerMyRun free?
CheerMyRun is free to download, with in-app purchases. You can see the available plans and prices in the app.
Is this the official race tracker?
CheerMyRun adds live GPS tracking and voice cheers from your family. It is independent of the organizer and does not replace the official race tracker, chip timing or results.
Your people. With you all the way.
